Abstract
A method for frequency-dependent noise suppression in an input signal is particularly suited for a hearing device. The input signal is distributed to a main signal path and an ancillary signal path. The presence of a useful signal component and, if a useful signal component is present, a parameter for a frequency of the useful signal component are assessed in the ancillary signal path. Noise in the input signal is suppressed in the main signal path by at least one infinite impulse response filter whose frequency response is implemented with a maximum absolute value in the range of that frequency of the useful signal component that is assessed using the parameter by determining a complex pole of the transfer function. The complex pole of the transfer function is determined by using the assessed parameter for the frequency of the useful signal component.
